Build a Smiley-Faced Weather Station with Arduino Nano — STEM Kit for Kids

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Watch your child light up as the OLED screen shows a happy face when the room is comfortable, and a frown when it’s too hot or humid. This Arduino Nano weather station kit introduces I2C communication and C++ structs through fun, visual feedback. Perfect for young makers eager to move beyond blinking LEDs and tackle real sensor-driven projects.

What You'll Build

You’ll assemble a standalone mini weather station that reads temperature and humidity from a DHT11 sensor and displays the values on a crisp 0.96-inch OLED. The fun part: the display shows a smiley face when conditions are pleasant, and a sad face when they’re not — all coded by you. It’s a great conversation starter you can keep on your desk or gift to a curious friend.

What You'll Learn

• Wiring I2C devices (OLED display) to an Arduino Nano
• Reading digital sensor data from DHT11 using the DHT library
• Using C++ structs to group temperature and humidity readings into a single variable
• Creating custom graphics on an OLED screen based on live sensor thresholds

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for students in CBSE-affiliated schools, especially those exploring projects in Atal Tinkering Labs (ATL). It’s also a great fit for 10-12-year-olds across India who have tinkered with basic LEDs and now want a meaningful first Arduino project. The clear visual feedback on the OLED keeps motivation high, and the code introduces core programming concepts without overwhelming a young learner.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
